Third Circle is an independent Irish microbrewery that has its beginnings in Kilcoole, Co Wicklow, where Third Circle director and brewer Jon Grennan grew up. In common with many Third Wave craft brewers, Jon's journey into the industry began with home brewing where he developed a fascination and love for the art and science of beer.

Third Circle beers are now crafted in Dublin at Third Barrel Brewery, where Jon's love for both precision and experimentation are feeling the creation of some exciting new brews. The company's core beliefs are simple: brew with balance, good taste and curiosity. Third Barrel Brewery was founded in Bluebell Avenue, Dublin in collaboration with friends at Stone Barrel Brewing.
